When should you import a PST file to Outlook?

Outlook usually automatically creates a PST file with all mails, notes, tasks and calendar entries. You can import this Personal Store, PST for short, as an Outlook archive. This is useful for restoring all data on computers in the event of a system crash. The PST file is created when you save it on your PC or is stored in a mailbox that is located on the server. A major advantage of this method is that by backing up the data in a PST file, all Outlook data is physically located in one place, so you can access it whenever you need it.

Restoring unsynchronized Outlook data

Importing a PST file to Outlook is useful when you swap your PC but haven’t synchronized your data via a cloud beforehand. This may be the case if the synchronization was unwanted, for example, because of data protection rules in a company. In this case, exporting all Outlook data, transferring it to a storage medium and subsequently importing it to a new system can be the simplest and fastest solution. This way, users can ensure that all data is restored on the new computer, instead of only certain types of data.

When you import PST files, emails, tasks and old and pending calendar entries will all be integrated. You’ll also be able to import all your import Outlook contacts.

Merging Outlook accounts into a single view

Some users have multiple accounts that they use at the same time. For improved organization, it can be helpful to merge these accounts into one client. Outlook provides a folder structure that neatly displays multiple accounts in a clear manner. If you want to do this, you can export an account as an archive and then merge it with an existing account on the computer you want to use to manage the different accounts. This way, you only have to import the PST file once.

This can be rather practical when an employee leaves a company and the person that replaces them needs to access existing data to create extensive Outlook distribution lists, for example.

Archiving unused data

Storing all data in a PST directory effectively archives all unused Outlook information. However, if your goal is only to save emails, you can simply archive Outlook mails.

If you want to view an overview of all appointments on another computer, you can easily share the Outlook calendar. This allows you to reschedule or postpone meetings on the go using your smartphone.

Tip

With Microsoft 365, users not only gain access to a variety of the most powerful Office products on the market. With the associated OneDrive storage, you synchronize emails and calendar entries and conveniently access your Outlook from other devices, for example via the browser.

How to import a PST file as an Outlook data file

Outlook offers users a convenient way to integrate archived folders, allowing you to add PST files and use them as a subfolder.

Attaching a PST file to your Outlook account lets you view stored data in a separate section in your Outlook profile (see screenshot step 3). The benefit of this is that the data stays separate from your current email and calendars, appearing in its own section in the overview on the left. If you prefer, you can also integrate it into your existing profile so that it’s not kept separate from the current data.

Follow the steps below to add PST files to Outlook directly.

Step 1: Click on File in the upper navigation bar and then on Open & Export and select Open Outlook Data File.

“Open Outlook Data File” in Outlook menu “File” > “Open & Export”
The “Open & Export” function has four options. Select the second to open an Outlook data file.

Step 2: Once you have clicked on the menu item, a window will open where you can select which file you want to import. In the example below, the Outlook.pst is located under User > Username > Documents > Outlook Files. Select the file and click Open.
